Super explaination Brian :)
Currently the only way to fix mailbox profiles would be a manual profile repair within Outlook, by publishing an Office PRF file via GPO (not going to work for non-domain joined machines), or by decommissioning the CAS server named in the users’ profiles so the endpoint is no longer available. This last option should (test test test!!) trigger a full profile repair by Autodiscover in Outlook 2007 or Outlook 2010. Outlook 2003 is only repairable with a profile repair or a PRF file
Here if we want the clients to update their profile to point to the Cas-array in the main site(once the CAS-array in the main site is back up and running), instead of decommisioning the CAS in the DR site , can we just stop the services in the DR server or something else ?
